FAQ
Q: Is it possible to convert the DC supply through the same coaxial cable LMR 400
A: Evet, sizin için özelleştirebiliriz.
Q: Can you make a frequency UP / Down Converter with a UART port where we can change the LO?
We want to shift up 750-1050 to 3100-3300 and we also wish to have the opportunity to change LO to shift up 750-1050 to 3500-3800 or 4100-4400 ve kadar 4600-4900 Örneğin.
A: Most of the time, the LO is fixed. If you want to test a trial sample with adjustable LO, we can also do the sample for you.
If it’s a fixed Lo, we can test it and take a video for you, and you won’t have a problem using it. If it is adjustable, we can also reserve this interface, but if it is easy to fail by the user modifying the LO, the engineer is a little worried at this point.
BDC is a block down converter. L-band up converters, down converters, and block converters, covering a frequency range of 200MHz to 3.8GHz.
Q: Can you make the frequency down converter in this frequency range? From 5750-5950Mhz to 200-400Mhz?
Aşağı Dönüştürücü: RF girişi 5750-5950 MHZ IF out 200-400 MHZ Local oscillator 5550 MHZ
A: We can not do it. The oscillator frequency 5550Mhz is too high, our max is 4200M.
Q: What is the overall passband flatness of the down-conversion module?
A: The down-conversion module provides a passband flatness of ≤ 6 dB (zirveden zirveye) over an 8 MHz bant genişliği.
This means that within the specified 8 MHz passband, the maximum variation in conversion gain does not exceed 6 dB.
Notlar:
-
The flatness specification is defined as peak-to-peak gain variation, not ±6 dB
-
The specification applies under nominal operating conditions
-
Passband flatness may vary slightly depending on frequency configuration and operating environment
Q: Can the module be powered by a standard power outlet, and can the operating temperature range be extended to –40°C to +70°C?
A: The use of a standard power outlet (via an external power adapter) is feasible at the system level, provided that an appropriate industrial-grade power supply is selected and properly integrated.
The operating temperature range of –40°C to +70°C is typically a system-level requirement. Achieving this temperature range depends on the overall system design, including enclosure, termal yönetim, güç kaynağı, and environmental protection.
For the down-conversion module itself, supporting continuous operation over –40°C to +70°C would require the use of military-grade or extended-temperature components, which significantly impacts component selection, maliyet, and lead time.
Notlar:
-
Standard commercial-grade components usually support a more limited temperature range
-
Extended temperature operation must be evaluated on a case-by-case basis
-
Please contact us if –40°C to +70°C operation is a mandatory requirement, so feasibility and cost can be assessed accordingly
Q: Merhaba, can the down converters we bought from you be changed to cut the LO frequency in half? They currently operate at 1750 MHz—can they work around 875 MHz or be set to 750 MHz?
A: Evet, the LO (Yerel Osilatör) frequency can be modified. Fakat, we strongly recommend that the modification be carried out by our engineers, or that you return the unit to us for adjustment to ensure optimal performance and stability.
If you prefer to modify it yourself, it is also possible by following the procedure below. how to adjust LO frequency to control IF output frequency
